Intrusive luxation is a kind of traumatic injury characterized by an axial displacement of the tooth toward the alveolar bone. Its main causes are bicycle accidents, sports/recreational activities, and falls or collisions. Treatment strategies include waiting for the tooth to return to its position, immediate surgical repositioning and repositioning through dental traction by orthodontic devices. The correct diagnosis must be based on clinical and radiographic exams and it is crucial for decision-making in the treatment of injured patients. Currently, the cone beam computed tomography (CBCT) has been widely used in orthodontics, restorative dentistry and implantology as well as in the diagnosis of complex dental trauma. This article reports a case of severe dental intrusion, in which the cone beam computed tomography (CBCT) was performed because of doubts generated after clinical examination and panoramic radiograph analyze. This case report confirmed that the CBCT is an important exam to correct diagnostic.

Objectives: The aim of our study was to highlight the advantages of using Cone Beam Computed Tomography in the study of the extent of the alveolar bone loss, compared to the conventional intraoral radiography and to prove the boon of the CBCT scans for establishing the correct periodontal diagnosis. Material and methods: A total of 16 patients with age between 35-55 years old, and a minimum of 8 teeth per dental arcade, presenting peridontal clinical symptomatology were selected. We used a custom periodontal chart that included the measuring of the gingival recession and the pocket depth in 6 points for 16 teeth, 8 maxillary teeth and 8 mandibulary teeth in all cases. For the radiographic evaluation we used CBCT imaging and intraoral radiography. Results: CBCT scans offers the possibilities of measuring with accuracy the alveolar bone loss on mesial, distal vestibular and oral sides. It provides images with the exact position of the bone and also the expediency to assess the correct diagnosis. Retroalveolar radiography offers just a hint of the possible position of the alveaolar bone in all cases the anatomical details were offered by CBCT. Conclusions: A correct periodontal diagnosis using conventional radiography is not possible because of the superimposition of the anatomical structures. The importance of CBCT imaging is no longer disputed, at the present time it is the best radiographic investigation available.

Abstract Lateral luxation injuries are one of the most severe periodontal injuries in dental trauma. The correct diagnosis followed by repositioning of the tooth on the right position is fundamental for the periodontal ligament healing. This study reported a clinical case of lateral luxation of maxillary central incisor involving a new cone beam computed tomography (CBCT) software for reconstruction (e-Vol DX) to confirm the lateral luxation after no conclusive dental trauma injury definition by using conventional exam. The lateral luxation injury was digitally reduced by insertion of tooth back to its alveolus, and at the same session, the tooth was stabilized with a rigid splint and further changed to a semi-rigid nylon splint. During the pulpal status monitoring, the pulp was diagnosed necrotic, then the root canal was treated to prevent root resorption. External office-bleaching and restorative procedure was performed. The 4-years follow up and new imaging exam and digital reconstruction confirmed bone healing and no complication. CBCT images analyzed by eVol DX can be used to determine and to guide lateral luxation treatment.

Objectives: The purpose of this case report is to analyze the incidental finding of an odontogenic keratocyst on cone beam computed tomography (CBCT) examination for the case of an impacted tooth 48. Case Report: A 48-year-old man came with a consul letter to perform a CBCT examination with complaints of loose teeth on the right posterior mandible starting from the premolars. Coincidentally found on a sagittal view showed a wide radiolucency lesion on the internal part of the jaw and not related to the impacted tooth. The treatment plan is to remove the lesion and perform a biopsy and perform postoperative panoramic radiograph. Conclusion: The characteristics of the odontogenic keratocyst lesion can be visualized clearly on CBCT. The use of CBCT in analyzing the type and size of the lesion is very helpful in planning surgical treatment. Odontogenic keratocysts can be well-diagnosed using a combination of CBCT examination with histopathological examination to determine the most effective management and prevent a recurrence.

Abstract Background Radiographs are integral in evaluating implant space and inter-root distance. The purpose of this report is to introduce a method for evaluating the 3D root position with minimal radiation using a 3D tooth model composed of an intraoral-scanned crown and a cone-beam computed tomography (CBCT)-scanned root. Materials and methods Intraoral scan and CBCT scan of the patient were obtained before treatment. In the CBCT image, tooth segmentation was performed by isolating individual teeth from the maxillary and mandibular alveolar bone using software program. The 3D tooth model was fabricated by combining segmented individual teeth with the intraoral scan. Results A post-treatment intraoral scan was integrated into the tooth model, and the resulting position of the root could be predicted without additional radiographs. It is possible to monitor the root position after a pretreatment CBCT scan using a 3D tooth model without additional radiographs. Conclusion The application of the 3D tooth model benefits the patient by reducing repeated radiation exposure while providing the clinician with a precise treatment evaluation to monitor tooth movement.

Abstract Purpose The aims of this retrospective cross-sectional study were to measure and compare labial and palatal alveolar bone heights of maxillary central incisors in unilateral cleft lip and palate patients, following STROBE (Strengthening the Reporting of Observational Studies in Epidemiology) guidelines. Patients and methods The study group consisted of 21 patients with a mean age of 16 years. High-resolution cone-beam computed tomography was performed at least one year after secondary alveolar bone grafting. The experimental side was the cleft side and the contralateral side without congenital cleft was the control. Measurements were performed on incisors’ midsagittal cross-sections. The Wilcoxon signed-rank test was used for intergroup comparisons. Results The labial and palatal distances between alveolar bone crests and cementoenamel junctions were significantly greater on the cleft side than on the noncleft side. Mean differences were 0.75 and 1.41 mm, respectively. The prevalence of dehiscences at the cleft side maxillary central incisors was 52% on the labial surface and 43% on the palatal surface. In the controls, it was 19% and 14%, respectively. Conclusion The cleft-adjacent maxillary central incisors had more apically displaced alveolar bone crests on the labial and palatal sides of the roots than the controls. Higher prevalence of dehiscences was found on the cleft side. Bone margin differences predispose to gingival height differences of the central incisors. These differences could increase the demands of patients to obtain more esthetic treatment results with orthodontic extrusion and periodontal intervention on the cleft side.
